Changing Fractions
1. Imprper fractrion into mixed number.
E.g. Change \(\frac{17}{2}\) into mixed number.
Answer:
\(\frac{17}{2}\) can be written as 17 ÷ 2
so \(\frac{17}{2}\) = 8\(\frac{1}{2}\)
2. Mixed number into improper fraction.
E.g. Change 2\(\frac{1}{2}\) into fraction.
Answer:
2\(\frac{1}{3}\) = 2 × 3 = 6
2\(\frac{1}{3}\) = 6 + 1 = \(\frac{7}{3}\)
